keep w/in the terms of service (reward companies with reasonable terms of service). IOW, I don't want to sign up with someone who says only one person can use the service and then occasionally use it.

I think Earthlink's policy is reasonable, although I my case I'd prefer the AOL approach (if another user is logged on, you can't). I don't expect much if any double use, since my use will be very occasional (testing + traveling).
